A few days ago, the results of a new method of gene therapy aimed at “altering” the necrosis of the spinal cord were published. It's about the scars left after physical damage to the spine, which the neurons share and do not allow nerve cells to exchange signals. Scientists succeeded in replacing this useless tissue with normal, lively, partially restoring the spinal cord.
With spinal injuries, both the control nervous system and the muscles controlled by it remain, but the connection is lost between them. Its restoration is the main goal of all works in this direction. In experimental mice completely paralyzed, a few weeks after the gene therapy, it became possible to move the paws. Over time, they again began to crawl (but not yet walk), and then began to independently seek and absorb food.
Most of all scientists were struck by the fact that the animals recovered and fine motor skills, for example, they could grab and gnaw pieces of sugar of different sizes. This means that the task can be divided into several stages and, for example, to achieve the restoration of control over the hands of a paralyzed person, even if he still has to spend the rest of his life in a wheelchair.
Experiments on mice were of a research nature, and the technique is not yet ready for adaptation for humans.js.src = “&version=v2.8”; 'script', 'facebook-jssdk'));
